IMPR OVEME NT IN WHEEL-CULTIVATORS.

Specification forming part of Letters Patent N 0. l82,l38, dated September .12, 1876; application filed May 22, 1876.

To all whom it may concern Be it known that I, THOMAS R. WALLIS, of Eggs Point, Washington county, State of Mississippi, have invented a new and Improved Wheel-Cultivator, of which the following is a specification My invention consists, mainly, of a novel contrivance of frames for coupling the bodyfrarne of a wheel-cultivator to the short inde composed of the elliptic plates G and connecting-bolts H, the plates being fitted at the middle on the. axles, so that they can be readily taken off and shifted higher or lower, for which a number of holes, I, are made in the plates G for the axle; and I connect the arch-standards O by making the lower ends to terminate in the bolts H, employed forcoupling the plates G, which I effect by bending them at right angles as much above the lower ends as the required length of the bolts, and passing them through the plates. I also arrange them in an eye-stud, K, on the inner plate G, to keep the plate in contact with the upright part. L represents the coupling for the plow-beams M, which consist of a broad plate with an eye to fit on the rear bolt H, and two or more sockets, N, for the beam, to set it nearer to or fartherfrom the row of plants, and with a lateral extension, 0, at one side for increasing the range of lateral adjustment by reversing the The elliptical form of the plates G affords the strength required with the smallest quantity of material. By the use of these plates,

aside from the advantages already stated, the.

couplings are placed several inches in rear of the axle, and when cultivating uneven ground the plows are automatically adjusted to plow the same depth as when used on level surfaces. Much more space is given between the arch and wheels for lateral movements of the plow-beams. I

Having thus described my invention, what I claim as new, and'desire to secure by Letters Patent, is-

1. Theaxle-frames, consisting of elliptical plates G and connecting-bolts H, combined with the short axles B and the arch-standards G, substantially as herein shown and described.

2. The bolts H, formed on the arch-standards O, and combined with plates G, substantially as herein shown and described.
